1 Claim.

This invention pertains to an engine mounting, and more particularly to novel means for attaching an internal combustion engine beneath the bottom of a machine, utensil, implement, and

5 the like.

Heretofore, considerable difiiculty and expense has been encountered in attaching motors below various types of apparatus designed for selective operation by either electric or internal combustion motors, each requiring special forms of mounting, and, in some instances, changes in the structure of the apparatus itself.

It is therefore the primary object of the present invention to overcome the foregoing difiiculties by the provision of an exceedingly simple, compact, and inexpensive engine attachment, for the purpose set forth, which will permit ready interchangeability with an electric motor.

Incidental to the foregoing, a more specific ob- 20 ject of the present invention resides in the provision of a mounting bracket attached to the lower side of the bottom of various apparatus, such as machines, utensils, implements, and the like, and having a vertical driven shaft journaled therein for operative connection with an internal combustion engine attached to the lower portion of said bracket, and provided with a horizontal drive shaft, said bracket being interchangeable with an electric motor as hereinafter described.

With the above and other objects in view, which will appear as the description proceeds, the invention resides in the novel construction, combination, and arrangement of parts, substantially as hereinafter described, and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claim.

In the accompanying drawing is illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode so far devised for the practical application of the principles thereof.

The single figure is an elevation illustrating a mounting bracket constructed in accordance with one form of the present invention, and having attached thereto an internal combustion engine of conventional structure.

Referring now more particularly to the accompanying drawing, the numeral I designates the bottom face of any type of conventional machine, utensil, implement, or the like, to which it is desired to attach a prime mover in the form of an internal combustion engine or electric motor. As set forth in the objects, the invention consists primarily in the provision of a bracket 2, in which a vertical driven shaft 3 is journaled, and provided at its upper end with a power takeoff 4, which in the present illustration comprises a pulley for the reception of a V-type belt. However, it will be apparent that the pulley 4 may be readily replaced by a sprocket, gear, or other transmission means.

It will also be understood that the shaft 3 may be journaled in any suitable manner in the bracket 2, but for the purpose of illustration the upper and lower ends of the bracket are provided with bearing bushings 5.

The lower end of the bracket is provided with an enlarged transmission housing 6 to accommodate an operative connection between the driven shaft 3 and the motor shaft I, which in the present instance comprises bevel gears 8. One side of the housing 6 is provided with an opening 9 through which the motor drive extends, and surrounding the opening is a pad or flange Ill to which the motor II is attached in any suitable manner. In the present illustration of the invention, the motor I I is of a conventional internal combustion type.

The upper end of the bracket 2 is preferably provided with a flange I2 attached to the under side of the bottom I by means of the bolts I3, or any other suitable means, the salient feature of the invention residing in the provision of a compact bracket for attachment to the bottom of various types of apparatus, and having a vertical driven shaft journaled therein and operatively connected with a motor attached to the lower end of the bracket in the manner heretofore described, the drive shaft of the motor being positioned horizontally.

In the event it is desired to substitute an electric motor for the internal combustion engine II illustrated in the drawing, it is merely necessary to remove the bracket 2, and attach an electric motor Y tothe base I of the machine by the attaching studs I3, the motor being indicated in dotted lines on the drawing.

From the foregoing explanation, considered in connection with the accompanying drawing, it will be readily seen that an exceedingly simple, compact, and inexpensive mounting has been provided for attaching an internal combustion motor to the bottom of various types of apparatus. It will also be apparent that a. mounting of the present type not only facilitates attachment of the motor, but permits replacement of an electric motor without interchanging of parts of the apparatus.

The present invention has been illustrated and of a machine base and having a portion extending described as applied to a motor drive projecting through the bottom of a machine, utensil, implement, or the like, but in some instances, such as in connection with washing machines, separators, and the like, the invention may be applied to a suitable base plate positioned below the apparatus.

While one specific application of the present invention has been illustrated and described in detail, it is to be understood that variations in design and mechanical details are contemplated as within the invention to be hereinafter claimed.

I claim:

The combination of a motor, a mounting for said motor comprising an integral, verticaLhollow bracket for attachment to the lower face the upper end of the bracket for reception of a' power take-off, and a gear secured on said shaft within said gear cavity for operative connection with the shaft of said motor.
